How long are the tubes on your headers. I have everything else figured out and would like to know what you guys are running for header length. Having a starting point would save a lot of time from having a header made and adding pipe till i get the pulses to converge.

do some reading, its all over the map, depending on application.

i'm copying the MFR system, cause ive got the rest of that setup. they used 230cm long primaries. ideally mine will be adjustable so i can go to the dyno and change lengths, as i'd much rather have a strong 4500-8000rpm midrange, vs peak power @10k
